VDAT:

VDAT (VDAT Data Access Toolkit) is a set of products to streamline access to clean, integrated, reliable data. It consists of the following components:

• ETL: An ETL (Extract, Transform, Load) process, which pulls data from various sources, integrates and cleans, and stores the resulting data in a compressed binary format within HDFS (Hadoop Distributed File System).
• Hive: A command line tool for running SQL-like queries against the cleaned data. Our Hive library is customized to encapsulate logic from our beacons, logical definitions, and custom functions.
• Scheduler: A web service for programmatically running Hive queries, scheduling queries to run in the future, and retrieving the resulting data in various formats.
• Scheduler Web UI: A web application, which provides a front-end to the Scheduler along with basic tools for retrieving the resulting data.

Kingfisher:

Kingfisher is an infrastructure project initiated to migrate existing brittle pixel infrastructure to efficient, error tolerant and performance oriented system using Scribe, Hadoop, Map Reduce aggregation and Hive. Kingfisher hosts a bunch of http loggers, which pushes the logs into scribe and streaming to the HDFS.

For Efficiency and validation of these logs, Custom MRs were written which serialize and de-serialize the logs, validate them and feed the logs through to the ETL processing.

The ETL System consisted of Pentaho, Hive and Web UI. The ETL System would receive the Valid feed execute the Summarization every 1 hour, 4 hour and 24 hour intervals into multivariate dimensions and provide it to the Web UI.

Responsibilities:
Involved in designing Loggers / Scribe and HDFS upload.
Involved in the Hive Query Designs and Pentaho Integration with Hive using Hive Webserver.
Implementing the ETL System that would summarize the valid logs at regular intervals.
Involved in setting up data validation tools to compare beta release data with legacy system data
Involved in the Capacity assessment of the Hadoop Cluster.

Cost:
ETL is an infrastructure project initiated to migrate existing shell script based SEMTools reports to performance oriented distributed systems of Hadoop. Querying capabilities of this Distributed reports was developed using hive. The complete workflow was controlled through ETL processing tool, Pentaho.
The migration from the shell script

Responsibilities:
Involved in designing pentaho workflow for report processing.
Implementing pentaho components to download cost, hadoop storage, executing hive summarization queries and load to MySQL tables.
Involved in setting up data validation tools to compare beta release data with legacy system data
Implementing search query report analysis, positizing and negatizing keywords using Hadoop storage and Hive custom MRs.

Environment: Jdk 1.6, Spring IOC 2.0, apache tool packages, JUnit, Pentaho ETL, Hadoop, Hive, Shell, Ubuntu, MySQL, Git VCS, Maven, Jetty web server.

Adsleuth: 
Historically, Ask.com displays all ads returned by Google without considering their performance on our site. AdSleuth project intends to measure the performance (CTR) of an advertiser’s domain on our site in real time and when a low-CTR domain is returned by Google for a query, request fewer ads for subsequent occurrences of that query in the immediate future (a few minutes). Following this strategy, AdSleuth expects to show fewer ineffectual ads in response to the users’ queries.

Our initial experiments indicate that since many queries and ads repeat within short intervals of time, AdSleuth can remove a large portion of ineffective impressions while foregoing a relatively small number of picks. Our analysis also indicates that the ratio of reduced impressions to lost picks for AdSleuth is much larger than the same ratio achieved by the recent ad-reduction on direct US and UK traffic by a raw optimization method that does not consider the domain CTR.
